Can You Add an Inverter to a Generator?

As the world increasingly embraces renewable energy sources, many individuals and businesses are turning to solar power as an efficient and sustainable solution. Solar energy not only reduces reliance on traditional grid-based electricity but also offers the potential for cost savings and environmental benefits. However, for those who already own a generator, integrating solar power may seem like a complex task. In this article, we will explore the possibility of adding an inverter to a generator and discuss the benefits it can bring to your energy setup.

1. What is an Inverter for a Generator?

Before we delve into the process of adding an inverter to a generator, it's crucial to understand what an inverter does. In simple terms, an inverter is an electronic device that converts direct current (DC) power into alternating current (AC) power, which is the type of electricity commonly used in households and businesses. In the context of a generator, an inverter helps regulate the power output and ensures a stable flow of electricity to the connected devices.

2. Difference between Generators and Inverters

Generators and inverters serve distinct purposes when it comes to generating electricity. A generator operates by burning fuel, such as gasoline, diesel, or propane, to produce mechanical energy that is then converted into electrical energy. It generates AC power directly, but the voltage and frequency may not be as stable as that from a utility grid.

On the other hand, an inverter primarily focuses on converting DC power into clean and stable AC power. It takes input from various sources such as solar panels, batteries, or even a generator, and ensures a consistent and reliable power supply. Inverters are commonly used in solar power systems to convert the DC energy captured by solar panels into usable AC power.

3. Inverter Generator vs. Regular Generator

An inverter generator combines the best of both worlds by integrating an inverter within a traditional generator setup. Unlike conventional generators, inverter generators use advanced electronics to produce a more stable and consistent flow of electricity. They offer numerous advantages, including:

a. Clean Power: Inverter generators produce "clean" power, characterized by stable voltage and frequency, making them ideal for powering sensitive electronics such as laptops, smartphones, and medical equipment.

b. Fuel Efficiency: Inverter generators optimize fuel consumption by adjusting the engine speed based on the power demand, resulting in improved fuel efficiency and reduced noise levels.

c. Lightweight and Portable: Inverter generators are generally more compact and lightweight than conventional generators, making them easier to transport and store.

4. Do I Need an Inverter for My Generator?

Whether you need an inverter for your generator depends on your specific energy requirements. If you primarily use your generator for powering appliances and equipment that are tolerant of fluctuations in voltage and frequency, a regular generator may suffice. However, if you plan to use sensitive electronics or require a stable power supply, integrating an inverter becomes highly beneficial.

5. How to Add an External Inverter for a Generator?

Adding an external inverter to your existing generator can enhance its functionality and make it compatible with solar power systems. Here's a step-by-step guide on how to integrate an external inverter:

Step 1: Assess Compatibility: Ensure that your generator is compatible with external modifications and can accommodate an inverter. Consult the generator's user manual or reach out to the manufacturer for specific details.

Step 2: Select an Inverter: Choose a solar inverter that suits your power requirements and is compatible with your generator. Consider factors such as power output, efficiency, and any additional features you may need.

Step 3: Wiring and Connections: Connect the output of the generator to the input of the inverter using appropriate wiring and connectors. Follow the manufacturer's instructions and adhere to safety guidelines while making the connections.

Step 4: Configure the Inverter: Configure the settings of the inverter to synchronize with the generator's power output. This step may involve adjusting voltage, frequency, and other parameters to ensure compatibility and smooth operation.

Step 5: Test and Monitor: Once the inverter is connected and configured, conduct thorough testing to verify its functionality. Monitor the power output and assess the stability of the electricity supplied by the integrated system.


Integrating an inverter with a generator allows you to combine the reliability of a generator with the stability and clean power of an inverter. By adding a solar inverter to your generator setup, you can harness the benefits of solar energy while enjoying a consistent power supply. However, it is crucial to assess your specific energy needs and ensure compatibility before undertaking the integration process. Always consult the manufacturer's guidelines and consider seeking professional assistance for a seamless and safe integration of an inverter to your generator.
